• Upper-transportation position Lower-transportation position
The junction gate moves to the lower transportation position when the trailing edge of the
paper reaches the point 10mm after the junction gate. (Paper position is based on the
entrance sensor, and is controlled by motor pulses.)
• Lower-transportation position Upper-transportation position>
The junction gate moves to the upper transportation position when the trailing edge of the
paper reaches the guide fence, and the trailing edge presser moves to the press position.
• Trailing edge presser (Reverse roller)
• Press position Pressure release position>
The trailing edge presser moves to the pressure release position when the trailing edge of the
paper reaches the reverse roller.
• Pressure release position Press position>
The trailing edge presser moves to the press position when the trailing edge of the paper
reaches the guide fence.
The junction gate motor rotates clockwise, and switches the junction gate and the trailing edge presser
(reverse roller). The positions of the junction gate, trailing edge presser and reverse roller vary as
follows.
* The home position is at “Junction gate: Upper-transportation position” and “Trailing edge presser:
Pressure release position”, and is detected by the junction gate motor HP sensor.
Sub-scan direction (transport direction) jogger mechanism
Paper transported to the stacking area by the paper exit rollers is delivered to the reverse rollers. Paper
alignment for the sub-scan direction is performed by using the reverse rollers to press the trailing edge
of the paper against the guide fence.
